clear-mcp

A Model Context Protocol server that lets an AI agent read CLEAR's humanitarian data — signals, events, alerts, crises, situation analyses, and the knowledge base — through clear-api.

It is a thin, read-only adapter: it forwards your sk_live_ API key to clear-api's GraphQL endpoint and adds no data, authorisation, or credentials of its own. Every answer is bounded by exactly your clear-api permissions.

Install

You need two things whichever route you pick: the URL of a clear-api (e.g. https://api.clear.example.org) and a CLEAR API key (sk_live_…), minted at <clear-api>/portal. The key is the only credential the server holds; it is forwarded unchanged.

Set up with a prompt

Paste this into any agent that can fetch URLs and run commands, such as Claude Code, Codex, Cursor, a Grok bot or your own framework, to connect that agent. Fill in the URL first. Every file and the server are pinned to one release, so a setup can be repeated exactly. The agent reads the clear-connect skill from the public npm package, works out its own install route, writes its config, runs the smoke test and reports back:

Connect yourself to CLEAR's humanitarian data through the clear-mcp MCP server.

Follow the clear-connect setup skill exactly. Fetch and read these first:
- https://unpkg.com/@clear-initiative/[email protected]/skills/clear-connect/SKILL.md
- https://unpkg.com/@clear-initiative/[email protected]/skills/clear-connect/references/clients.md
- https://unpkg.com/@clear-initiative/[email protected]/skills/clear-connect/scripts/smoke.mjs  (the smoke test: save it and run it with node)
The other skills it mentions are at https://unpkg.com/@clear-initiative/[email protected]/skills/<name>/SKILL.md.
Use this one version everywhere: run the server as @clear-initiative/[email protected], and run the smoke test against it with `-- npx -y @clear-initiative/[email protected]`.

CLEAR API URL: <clear-api URL>
API key: read it from the CLEAR_API_KEY environment variable. Never print, log or commit it. If it is not set, stop and ask me to set it; do not ask me to paste it into this chat.
Role: reader, not a Task Worker.

Work out how you yourself run (client, framework, model API) and use the matching route. If you can only take a remote MCP URL, stop and tell me, because that is not supported yet. If you cannot run commands or change your own configuration, give me the exact steps instead.

When you are done, call clear_whoami and tell me the route, the pinned version, the role and teams it reported, how many clear_* tools you have, which skills you installed or added to your instructions, and anything I still need to do.

Before you paste it, mint the agent's own key at <clear-api>/portal, signed in as the agent's user (not your own), and have an admin approve that user. For other agents and frameworks, see Connecting another agent.

Install by hand

You use	Install	You get
Claude Code	the plugin — two commands	the server and the skills
Claude Desktop	the extension — open one file	the server, key kept in your OS keychain
Any other MCP client	npx -y @clear-initiative/mcp	the server
Another agent or bot (a Grok bot, OpenAI Agents SDK, LangGraph, Codex, …)	Connecting another agent, or have an agent run the clear-connect skill	the server, a smoke test, config for your framework

Claude Code plugin (recommended)

claude plugin marketplace add CLEAR-Initiative/clear-mcp
claude plugin install clear-mcp@clear

Or from inside Claude Code: /plugin marketplace add CLEAR-Initiative/clear-mcp, then /plugin install clear-mcp@clear. Claude Code asks for the CLEAR API URL and CLEAR API key when the plugin is enabled — the key goes to secure storage (the macOS Keychain, or ~/.claude/.credentials.json elsewhere), never settings.json — and an optional locale. To script it, pass them up front:

claude plugin install clear-mcp@clear --config api_url=https://api.clear.example.org --config api_key=sk_live_...

The plugin runs the npm package pinned to its own version (npx -y @clear-initiative/mcp@<version>), so the server and the skills that describe it always move together — claude plugin update clear-mcp@clear upgrades both (restart Claude Code to apply). Node 20+ must be on your PATH. Change the URL, key or locale later from the plugin's configure option in /plugin.

This repository is private, so the marketplace resolves for anyone with read access to it; others use the npx route and copy the skills by hand.

Claude Desktop extension

1. Download clear-mcp-<version>.mcpb from the latest GitHub Release.
2. Open it with Claude Desktop — double-click the file, or Settings → Extensions and install it from there — and confirm the install.
3. Fill in CLEAR API URL and CLEAR API key; leave Locale as en or set ar, fr or es.

Nothing else to install: the extension carries its dependencies and runs on the Node that ships with Claude Desktop, and Desktop stores the key in the OS keychain. Updates are a new .mcpb from a newer release. The Release is on this private repository, so share the file with Consumers who cannot see it.

Any MCP client (npx)

The server is published to npm as @clear-initiative/mcp and runs on Node 20+ with no install step.

Claude Code without the plugin (server only, no skills):

claude mcp add clear \
  -e CLEAR_API_URL=https://api.clear.example.org \
  -e CLEAR_API_KEY=sk_live_... \
  -- npx -y @clear-initiative/mcp

Claude Desktop without the extension, or any client with a JSON mcpServers config (Cursor, Windsurf, …):

{
  "mcpServers": {
    "clear": {
      "command": "npx",
      "args": ["-y", "@clear-initiative/mcp"],
      "env": {
        "CLEAR_API_URL": "https://api.clear.example.org",
        "CLEAR_API_KEY": "sk_live_..."
      }
    }
  }
}

Pin a version (@clear-initiative/[email protected]) if you want upgrades to be deliberate. This is also the route for the developer escape hatch: add -e CLEAR_MCP_RAW_GRAPHQL=1. The plugin and the extension deliberately cannot switch it on.

Then ask: "Who am I in CLEAR?" — the agent calls clear_whoami. "Find Darfur" — it calls clear_find_location and gets back locationIds to pass to every other tool.

Configuration

The plugin and the extension set these from their settings forms; with npx or from source you set them yourself.

Variable	Required	Default	Meaning
CLEAR_API_URL	yes	—	Base URL of clear-api, e.g. https://api.clear.example.org
CLEAR_API_KEY	yes	—	Your sk_live_… key; the only credential the server holds
CLEAR_MCP_LOCALE	no	en	Sent as x-force-locale; one of en, ar, fr, es
CLEAR_MCP_RAW_GRAPHQL	no	unset	1 enables the developer-only raw GraphQL escape hatch
CLEAR_MCP_WORKER	no	unset	1 registers the five Task Worker tools (claim, heartbeat, complete, fail, and the rejected-case-URL read) — for a Worker process only, see Worker tools
CLEAR_MCP_LOG_LEVEL	no	info	pino level; logs go to stderr only

Missing CLEAR_API_URL or CLEAR_API_KEY exits 1 with the variable named on stderr. An optional variable set to an empty string counts as unset.

Run from source

For contributors — needs Bun 1.x:

git clone [email protected]:CLEAR-Initiative/clear-mcp.git
cd clear-mcp && bun install
claude mcp add clear-dev \
  -e CLEAR_API_URL=https://<dev-clear-api> \
  -e CLEAR_API_KEY=sk_live_... \
  -- bun /absolute/path/to/clear-mcp/src/bin.ts

After bun run build, node /absolute/path/to/clear-mcp/dist/bin.js is the same server on Node — exactly what npm publishes.

Try it

Three layers, from no backend to real data.

1. Unit suite (no backend)

bun run test

Every test drives a real MCP client against the real server over an in-memory transport, with clear-api replaced by fixtures. This is what CI runs on every PR.

2. Poke at it interactively (no backend needed)

MCP Inspector gives you a browser UI to list the tools, read their schemas and call them:

CLEAR_API_URL=http://127.0.0.1:1 CLEAR_API_KEY=sk_live_x npx -y @modelcontextprotocol/inspector bun src/bin.ts

Against the published package instead of your checkout, swap bun src/bin.ts for npx -y @clear-initiative/mcp. With an unreachable URL every call returns isError with code UPSTREAM_UNAVAILABLE and the URL it tried, which is the shape you'll see whenever CLEAR_API_URL is wrong.

3. Against real data

You need a running clear-api and a key.

1. A clear-api. Either run one locally (bun dev in clear-api/, which needs its Postgres + PostGIS; see that repo's README) or use a dev/staging URL. Check it answers:

   curl https://<clear-api>/health
   

2. A key. Sign in to https://<clear-api>/portal and mint an API key. It starts with sk_live_. Your account must be approved (role viewer, analyst or admin); a pending account can run clear_whoami but every content read returns FORBIDDEN / PENDING_APPROVAL until an admin approves it.
3. Smoke it with Inspector using the real values, then call clear_whoami. A healthy answer looks like:

   {
     "caller": { "id": "…", "name": "You", "role": "viewer", "language": "en", "isActive": true, "defaultTeam": null },
     "teams": [{ "id": "…", "name": "Sudan", "slug": "sudan", "locations": [{ "id": "…", "name": "Sudan", "level": 0 }] }],
     "locale": "en",
     "escapeHatchEnabled": false,
     "apiUrl": "https://<clear-api>"
   }
   

   Then clear_find_location with { "query": "Darfur" } — the first hit's id is what every other tool wants as locationId / countryLocationId.
4. Install it by any route in Install with the real values, and ask in plain language:

   claude mcp add clear -e CLEAR_API_URL=https://<clear-api> -e CLEAR_API_KEY=sk_live_... -- npx -y @clear-initiative/mcp
   

   "Who am I in CLEAR?" → clear_whoami. "What's happened in North Darfur this month?" → clear_find_location, clear_count, clear_list_events. "What do reports say about displacement there?" → clear_search_knowledge_base, with reportId / sourceUrl / page range to cite.

If a tool call comes back with isError, read the code: UNAUTHENTICATED means the key is unknown or revoked; FORBIDDEN + PENDING_APPROVAL means the account awaits approval; UPSTREAM_UNAVAILABLE means the URL is wrong or the API is down. The same diagnostic is logged to stderr at startup by the self-check.

4. Live suite and drift check

With a dev/staging URL and three test keys (an approved viewer, a pending user, a revoked key):

CLEAR_API_URL=https://<clear-api> CLEAR_MCP_TEST_KEY_VIEWER=… CLEAR_MCP_TEST_KEY_PENDING=… CLEAR_MCP_TEST_KEY_REVOKED=… bun run test:live
CLEAR_API_URL=https://<clear-api> CLEAR_API_KEY=… bun run refresh-schema && git diff --stat schema.graphql

Nightly CI runs both against staging once the matching repo secrets exist (see .github/workflows/nightly.yml).

Tools

Tool	Group	What it does
clear_whoami	Orient	Caller identity, teams and their scope locations, locale, escape-hatch flag, API URL
clear_find_location	Orient	Place name → ranked locationIds (levels 0–2) with ancestors; level / withinLocationId narrowing
clear_list_alerts	Monitor	Paginated alerts with status, event severity/types, location, truncated text
clear_list_events	Monitor	Paginated events with severity, GLIDE types, signal count, location, truncated text
clear_list_signals	Monitor	Paginated signals with source, url, location, truncated text
clear_count	Monitor	Totals for signals/events/alerts, grouped by type / severity / day / week / month
clear_get_alert / clear_get_event / clear_get_signal	Monitor	One row by id, untruncated; event carries alert ids and up to 50 signal references
clear_search_knowledge_base	Retrieve	Hybrid dense + BM25 search over ingested reports; citable hits with untruncated passages (limit 1–20, default 5)
clear_list_crises / clear_get_crisis	Analyse	Curated crises with LLM title/summary; get adds scenarios and NRC SAF needs
clear_get_situation_analysis	Analyse	A country's situation-analysis snapshot, filtered to sections; history: true for the yearly series
clear_get_datapoints	Analyse	Aggregated quantitative figures for a location and window (yearly by default) with data-quality scores and source report ids
clear_list_figures	Analyse	Charts/maps/tables extracted from reports, cursor-paged, with transcription

List tools take limit (clamped to 1–25, default 10) and offset, and return { items, totalCount, hasMore, limit, offset }; text in list items is cut at 500 characters with truncated: true. Get tools return { item } untruncated, or { item: null }. teamId (from clear_whoami) narrows Monitor tools to a team's location scope; omit it for the global feed.

Developer escape hatch

With CLEAR_MCP_RAW_GRAPHQL=1 two extra tools appear — clear_graphql (run a raw read-only query, get raw data) and clear_schema_type (print a type's SDL from the snapshot, or list the root Query fields). Even here nothing but query operations ever reach clear-api: a mutation or subscription, or any document the snapshot does not validate, is rejected before any network call. Leave it off for non-developer consumers.

Worker tools

With CLEAR_MCP_WORKER=1 five more tools appear — clear_claim_tasks, clear_heartbeat_task, clear_complete_task, clear_fail_task and clear_rejected_case_urls — the Task Worker protocol over clear-api's generic Task queue (clear-api ADR-0010). The first four are the only writes clear-mcp can send, each a typed document pinned to the schema snapshot (ADR-0010 amending ADR-0002); the escape hatch still rejects every mutation. A Worker claims Tasks of exactly one kind — today event.impact_prior.web (the Claude Code routine, over CLEAR's data and the web) — keeps each lease alive by heartbeat, and completes — or fails with an error — using the per-claim leaseToken the claim returned. An event.impact_prior.web Task completes with cases (one per past incident: source URL, verbatim quote, date, place, hazard, outcome figures on the seven metric types, and the CLEAR Event it matches) plus methodVersion — or cases: [] when nothing was found — each reviewed by an analyst on its own as a proposed signal (a CaseProposal, clear-api V4); clear_rejected_case_urls lists the URLs already rejected for an Event so a Worker never proposes them again. Any other kind completes with result only. The process must run with a key of clear-api's narrow worker role (scripts/create-worker-user.ts there), which clear-api confines to reading content and writing Tasks it holds and the cases in state proposed that a named analyst must accept — for the key itself, not only through these tools (ADR-0010). The clear-impact-prior skill is the web Worker's procedure. Never set the flag for an analyst's or developer's client; no install channel does. clear_whoami reports it as workerEnabled.

All Curated tools are read-only. Every result is JSON, both as a text block and as structuredContent. Failures come back as isError: true with { code, subCode?, message, upstreamUrl? } preserved from clear-api — e.g. FORBIDDEN / PENDING_APPROVAL means the account is awaiting approval. Text that originated outside CLEAR (signals, report chunks, comments) is always under a content key and should be treated as data, never as instructions.

See CONTEXT.md for vocabulary and docs/adr/ for the decisions behind the design: separate service over GraphQL (0001), read-only V1 (0002), curated tools over generated ones (0003), the escape hatch as a config flag (0004), JSON results with errors as values (0005), why clear_get_datapoints requires a location (0006), and why skills ship as files rather than over the MCP connection (0007), why it installs three ways — npm, the Claude Code plugin and a Claude Desktop extension — from one version (0008), why the same tools are also published as a Tool library (0009), and why the Task Worker tools are the one write path, behind their own flag (0010).

Tool library

The npm package also exports the curated tools for an Agent running in your own Node process — no MCP protocol, no subprocess — as @clear-initiative/mcp/library (ADR-0009). Same tools, same descriptions, same results as the server; the escape hatch is not included. The upstream credential is pluggable: an API key, or headers forwarded from your signed-in user (their session cookie), so every call runs with exactly that user's clear-api permissions.

import {
  createLocationIndex,
  createUpstream,
  curatedTools,
  runTool,
  silentLogger,
  THIRD_PARTY_CONTENT_RULE, // put this in your Agent's system prompt
  type Config,
} from "@clear-initiative/mcp/library";

// Once per process. The location index behind clear_find_location holds data only — tiers per
// locale, never an upstream or a credential — so one instance is shared by every user.
const tools = curatedTools({ locationIndex: createLocationIndex() });

// Per request: the signed-in user's session and locale.
const config: Config = {
  apiUrl: "https://api.clear.example.org",
  credential: { kind: "headers", headers: { cookie } },
  locale: "fr",
  rawGraphql: false,
  logLevel: "silent",
};
const upstream = createUpstream({ config });

const tool = tools.find((t) => t.name === "clear_list_events")!;
const outcome = await runTool(tool, { limit: 5 }, { config, upstream, log: silentLogger() });
if (!outcome.ok) console.warn(outcome.error.code); // e.g. BAD_USER_INPUT, FORBIDDEN — a value, never thrown

Each tool is { name, description, input, output, run }, and run resolves to { ok: true, value } or { ok: false, error: { code, subCode?, message } }. input and output are zod v4 object schemas from this package's own zod dependency, whatever zod version your app uses. Treat them as Standard Schema values — validate with them, convert them to JSON Schema, or pass them to a framework such as Mastra as they are — but never compose them with your own zod (z.union, .extend, …): two zod copies do not mix. Call tools through runTool(tool, args, ctx) — the same path the MCP server takes: it validates args against input (invalid input is a BAD_USER_INPUT value) and then runs the tool. Set rawGraphql: false: the escape hatch is never part of the library, and clear_whoami reports this flag as escapeHatchEnabled. Locale is per upstream, never a tool argument.

The location index loads each locale's tiers once, through whichever request first needs them, and shares them across users — this relies on clear-api's locations(level) returning the same tiers to every Caller. Known limitation: the cache never expires, so locations added to clear-api appear only after a restart.

Pass signal in the context (runTool(tool, args, { …, signal })) to abort a tool's upstream requests when, say, the user stops an Agent turn; the tool returns a CANCELLED value. This needs Node 20.3+ (AbortSignal.any).

The library reads its own package.json at load, so it runs on Node only; in Next.js, list @clear-initiative/mcp in serverExternalPackages.

Skills

The tools tell an agent what it can call; the skills in skills/ tell it how to use them together — the five-tier data model, which tool answers which question, and the citation and third-party-content rules that make an answer trustworthy.

Skill	Use it for
clear-briefing	"What is happening in X?" — orient, locate, then work down alerts → events → signals, with the data model and filter reference alongside
clear-evidence	Numbers, sources and citations — knowledge-base search, datapoints with their data-quality scores, figures, situation analyses
clear-graphql	The developer escape hatch — exploring the schema and writing narrow read-only queries for fields the curated tools do not cover
clear-analysis-scope	Fixing what an answer is about — locations and/or a crisis plus a period — before spending calls; multi-district scopes and the subtree traps
clear-situation-analysis	A situation analysis for a scope in a fixed section order — summary, key figures, needs by severity, event picture, recent alerts — with a staleness check
clear-sitrep	Freezing an analysis into a dated, immutable Situation Report with a provenance record
clear-weekly-brief	The recurring weekly operational brief per area of operation — incidents, trend, analysis, draft advisories, media

The first three teach the tools; the next four are workflows over them, drawn from the Situation analysis PRD; clear-connect sets up the connection itself. They are plain Agent Skills (a SKILL.md plus references/), so any harness that reads skills from disk can use them. Three ways to install:

As the Claude Code plugin (recommended) — the plugin install above ships every skill together with the server that runs them, and claude plugin update keeps them in step.

From the npm package, which ships skills/ alongside dist/:

npm install -g @clear-initiative/mcp
cp -R "$(npm root -g)/@clear-initiative/mcp/skills/"* ~/.claude/skills/

By hand — copy any skill directory into ~/.claude/skills/ (all your projects) or a repo's .claude/skills/ (that repo only, versioned with it).

The Claude Desktop extension carries the server only; its skills are the same skills/ directories, added through whatever skill support your Claude app offers.

Skills are read-only instructions. They carry no credentials and grant no access: every tool call they describe still runs as your API key and nothing more.

Development

bun run test             # vitest — every test goes through an MCP client over InMemoryTransport
bun run lint
bun run typecheck        # runs codegen first
bun run build            # codegen + tsc → dist/ (Node 20+ compatible ESM)
bun run refresh-schema   # re-snapshot schema.graphql from a dev/staging clear-api
bun run test:live        # live suite; needs CLEAR_API_URL + CLEAR_MCP_TEST_KEY_{VIEWER,PENDING,REVOKED}
bun run build:mcpb       # build + stage + smoke-run + pack the Claude Desktop extension → build/*.mcpb
bun run set-version X.Y.Z  # bump package.json, plugin.json (and its npm pin) and the mcpb manifest together

The live suite (tests/live/) proves the three things fixtures cannot — a pending key gets FORBIDDEN / PENDING_APPROVAL, a revoked key gets UNAUTHENTICATED, a viewer key works — and skips cleanly when the env vars are unset or the target is unreachable. Nightly CI runs it with CLEAR_MCP_LIVE=1 (skip becomes failure) against staging, together with a schema-drift check.

schema.graphql is the committed copy of clear-api's SDL. Tool documents are typed against it by graphql-codegen (output in src/gql/, committed), and the test suite validates every outgoing document against it, so a renamed upstream field fails here before it fails against a server. Refresh it with CLEAR_API_URL / CLEAR_API_KEY pointing at a dev or staging clear-api (introspection is disabled in production) and commit the diff.

Releasing

One version covers all three install channels — package.json, .claude-plugin/plugin.json (including the npm version its server pins) and mcpb/manifest.json. tests/packaging.test.ts fails if they drift.

bun run set-version 0.2.0     # writes all three; commit it in a PR and merge
git tag v0.2.0 && git push origin v0.2.0

The tag runs .github/workflows/release.yml: the CI gates, then npm publish, then a GitHub Release with clear-mcp-0.2.0.mcpb attached. A tag with a prerelease suffix (v0.2.0-rc.1) publishes under npm's next dist-tag and marks the Release as a prerelease. Push the tag right after merging — until it publishes, the plugin on main pins an npm version that does not exist yet. bun run build:mcpb builds the extension locally into build/; CI uploads one from every PR as an artifact for trying in Claude Desktop. Why three channels and not one: ADR-0008.
